Abstract

The main objective of this study is to determine the factors that influence entrepreneurial intention. The research design uses a causal quantitative descriptive approach. The objects in this study were fashion traders as many as 100 respondents at the Small Industry Center. The data collection method uses questionnaires distributed to fashion traders. Data analysis in this study used multiple linear regression analysis, classical assumption test, r square test and hypothesis test, using the SPSS 26 data processing tool. The first stage in this research is to determine the indicators for each variable and compose statements that will be used as a questionnaire, then after the data is collected, it is tested for the validity of the questions for each variable along with its reliability. The second stage examines the relationship between entrepreneurial attitudes, entrepreneurship education, family factors, and entrepreneurial intentions. The next stage will measure the research results of each variable relationship.

Abstract

Penggunaan ABS daur ulang pada komposit semakin populer untuk mengurangi limbah plastik, namun kelemahan sifat mekanik menjadi tantangan utama. Penelitian ini bertujuan meningkatkan sifat mekanik ABS daur ulang dengan menggunakan serat Twisted Tandan Kosong Kelapa Sawit (TKKS) sebagai penguat. Serat TKKS diproses melalui alkalisasi menggunakan NaOH 5% dan dibuat menjadi komposit dengan orientasi serat 0°, 90°, dan 0/90° menggunakan metode manual forming. Pengujian meliputi kuat tarik, kekuatan impak, dan stabilitas termal melalui uji DSC. Hasil menunjukkan bahwa orientasi serat 0/90° memberikan sifat mekanik terbaik dengan kuat tarik sebesar 28,75 MPa, energi impak 25,55 kJ/m², dan stabilitas termal tertinggi pada suhu 251,5 °C. Optimasi orientasi serat dan perlakuan alkalisasi terbukti efektif dalam meningkatkan performa komposit ABS daur ulang.
